Life before container shipping
At a busy dock, crates, sacks, and barrels arrived in separate shipments. Workers sorted and moved the cargo, assembled loads for lifting, and stowed the goods inside ships. Unloading meant another sequence of handling. Machinery could lift groups of packages, while much repeated handling remained.
Keep the goods inside. Move the container.
Malcom McLean built a commercial transport system around detachable cargo containers. A loaded container could move from a truck to a ship while the goods stayed inside. Reducing repeated handling lowered labor costs and helped protect cargo from damage and theft.
On April 26, 1956, the converted tanker Ideal X left Port Newark for Houston carrying 58 containers. That voyage was a major milestone in McLean’s container-shipping business.
More goods within reach
Less work moving a shipment can make it less expensive to bring useful things to customers. Container shipping helped make products from distant manufacturers more accessible. McLean’s contribution connects to the everyday experience of finding goods from far away on local shelves.

FAQ
A shipping container is a reusable freight box designed to travel between compatible trucks, trains, and ships with its cargo inside. “Intermodal” means moving between different kinds of transportation. Shared specifications help the box fit the equipment that moves it.
TRY IT AT HOME
Build a shipping route. Deliver the same cargo with less work.
Build a little transport system together, then improve it. Your job is to deliver twelve packages from a factory to a toy store. First move the packages separately. Then try keeping them together in shipping containers.
Gather your supplies
- 12 large toy blocks to use as packages.
- 2 small, lightweight boxes that each hold 6 blocks.
- 3 trays, box lids, or simple cardboard vehicles: a truck, a ship, and a second truck. Both containers must fit all three.
- Paper labels for the factory and toy store. A timer and paper for counting are optional.
Choose blocks and supplies appropriate for your child’s age. Work on the floor or a low table, keep loads light, and have an adult do any cutting. A working crane, small magnets, or heavy suspended loads are unnecessary.
Build the route together
Arrange the route shown above. The factory and toy store can be labeled spaces on the floor. Put the twelve loose blocks at the factory. Trace how the cargo will travel before starting.
Give the job a purpose: “The toy store needs these twelve packages. Let’s get them there.”
Deliver the loose cargo
Move the packages one at a time at each handoff: factory to first truck, first truck to ship, ship to second truck, and second truck to toy store. Move the vehicles along the route between handoffs.
Find the repeated work
Look back at the route together: “We kept picking up all those packages. How could we move them together?”
Bring out the two cargo boxes. Try fitting them onto the trucks and ship before reloading. Explain: “The goods can stay inside this box while the box changes vehicles.”
Deliver with containers
Reset the same twelve loose blocks to the factory. Pack six blocks into each container. Move the two loaded containers through the same four handoffs. Keep the goods inside until the containers reach the toy store. Then unpack all twelve blocks.
Compare the complete jobs
For a fair comparison, start both rounds with loose blocks at the factory and finish with loose blocks at the store. Include initial packing, any lid opening or closing, and final unpacking when timing. Keep the route, cargo, and each person’s role as similar as practical.
If the second trip is not faster, investigate what took time instead of claiming a result you did not observe. Counting can make the difference clearer than racing.
SAME DELIVERY. LESS HANDLING.
Did our hands get faster, or did our plan give us less work to do?
| Method | Moves |
|---|---|
| Loose cargo12 packages × 4 handoffs | 48 |
| Container cargo12 moves to pack + 2 containers × 4 handoffs + 12 moves to unpack | 32 |
16 fewer cargo moves, including packing and unpacking.
One move means picking up a block or a loaded container and placing it at its next location. Vehicle travel, lid handling, and the effort of lifting different weights are not represented by that count, though travel and lids belong in an end-to-end timing comparison. This is not a measurement of actual shipping costs or a claim that every move takes equal effort.
Connect your discovery to McLean
You changed how the cargo was handled while keeping the delivered cargo the same. McLean’s business used the same central advantage: keep freight together as its container moves between vehicles. Real implementation also required suitable ships, lifting equipment, and an operating business.

“Now that the delivery needs less handling, what could we do with the time we saved?”
ACHIEVEMENT CAN STAND UP TO QUESTIONS
Ask the hard questions.
Yes. The International Container Bureau was established in 1933, before McLean’s famous voyage. Its early work concerned rail and road transport. McLean’s distinctive contribution was developing and expanding a practical commercial container-shipping operation.
